Order/DE
Well, one of the things I brought up was how I think it'd be cool to explore the beginnings of the formation of the Order of the Phoenix and the Death Eaters, given we have so many future members of both groups in game.
In short, I'd like to work with the game premise and have something happen on the outside of Hogwarts that influences actions on the inside. I particularly think it'd be interesting to explore how different kids across different houses and years would find each other in supporting their views, and as I have two characters who are officially neutral in canon (Septima and Amos), I'd like to see whether/how they get caught up in it all.
